Here are some signs that your rear brake pads may need replacing:

• Squealing or grinding noises: This indicates that the brake pads are worn down to the metal backing plates.
• Spongy brake lever feel: A soft or mushy brake lever indicates that the brake pads have worn thin and are not providing enough resistance.
• Visible wear on the brake pads: If you can see the metal backing plates of the brake pads, it’s time for a replacement.

Gathering the Necessary Tools and Materials

Before you begin, ensure you have the following tools and materials readily available:

• New rear brake pads: Ensure you purchase brake pads specifically designed for the Yamaha MT 125.

Post-Installation Checks and Safety Tips

After completing the brake pad replacement, it’s crucial to perform a few checks before riding your motorcycle:

• Check for brake lever free play: Ensure the brake lever has the correct amount of free play. Refer to your motorcycle’s manual for the recommended specification.
• Test the brakes: Gently apply the rear brake lever to make sure the brakes are working properly. You should feel a firm and consistent braking action.
• Bed in the new brake pads: After a few stops, the new brake pads will need to be “bedded in” to ensure proper performance. This involves gently applying the brakes several times to transfer a thin layer of brake material onto the brake disc. Avoid hard braking during this bedding-in process.
